ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM

Shortly after driving away, before reaching a highway on-ramp, I noticed smoke coming from the vehicle. I turned around and returned to the location. By the time I arrived, the vehicle was emitting black smoke, and shortly after, it was fully engulfed in fire before I could retrieve a fire extinguisher. Vehicle has a documented history of a known manufacturer recall related to an electrical/HECU component and a separate high-pressure fuel pipe recall, both reportedly remedied prior to this incident

Purchased my Kia on the XXX then on the XXX, My engine light came on and my car went into Safety Mode . I at once took it to Auto Zone and their test came back with P1326 Knock signal range / performance. I then looked it up and found that a recall was put out quite a while back called an [XXX] # took my car to Kia Dealership in [XXX]. They said I could bring it in that was on the XXX and if an appointment came open they would check but they did not have an opening til the 14th which was today and I was told it would be next week . Could someone please send me updated information concerning the 2018 Kia Sportage and the Knock Sensor [XXX] [XXX] [XXX] [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE

2018 Kia Sportage (78,051 miles). Vehicle is part of the Kia Engine Class Action Settlement due to severe internal engine defects. The engine suffers from catastrophic oil consumption, running almost completely dry three times in less than six months with no external leaks, meaning it is internally burning motor oil at a dangerous rate.This known engine defect caused severe consequential damage to the exhaust and emissions systems. On Aug 12, 2026, a Kia dealer technician diagnosed active code P0420. The technician's video inspection stated both the catalytic converter and O2 sensors are completely "out of specification." This double failure is a direct result of the engine defect blowing excessive liquid motor oil out of the engine block and down the exhaust pipe, fouling the sensors and melting the internal catalyst.This failure happened immediately after receiving the mandatory Kia Recall SC340 update (Catalyst Overheating Protection). The vehicle is under the 80,000-mile Federal Emissions threshold, but Kia is denying coverage based strictly on a calendar time limit. They refuse to take responsibility for emissions components destroyed by their settlement-recognized engine defect.This condition poses a serious safety hazard. Driving with heavily fouled O2 sensors and a failing catalytic converter causes poor engine performance, unpredictable stalling or hesitation during acceleration, and excessive unburned fuel vapors to enter the environment and potentially the cabin. I request the NHTSA investigate Kia’s refusal to cover secondary emissions damages directly triggered by their defective oil-burning engines.

ENGINE

The contact owns a 2018 Kia Sportage. The contact stated that while driving approximately 45 MPH, the vehicle lost automotive power with the accelerator pedal depressed. The check engine warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 64,813.

ENGINE

The engine consumes excessive oil due to the known Theta II piston oil control ring defect that the manufacturer documents in its own Technical Service Bulletin ENG222, covering this engine family across model years 2011 to 2024. The vehicle loses over one quart of oil per 1,000 miles with no external leak and no oil pressure warning. The manufacturer's authorized dealer completed the entire TSB ENG222 diagnostic protocol, which is itself a controlled test designed to isolate cause. The engine was sealed, and after 1,080 miles it was 1.5 quarts low. The dealer then performed the TSB's combustion chamber cleaning. After that repair, over 1,149 miles, the engine was 1.4 quarts low. The cleaning had virtually no effect on the consumption rate. Because the protocol sealed the engine and cleaned the combustion chambers and the consumption rate remained unchanged, the protocol itself mechanically excludes maintenance as the cause and isolates the failure to the internal piston rings. This is the exact defect TSB ENG222 was created to diagnose and repair. The defect has been reproduced and confirmed by the manufacturer's own authorized dealer through this protocol, and the vehicle is available for inspection upon request. Under the TSB, these results qualify the engine for replacement. The manufacturer nonetheless denied the engine replacement, citing a lack of oil change receipts rather than any technical evidence of neglect, despite its own diagnostic protocol having already ruled out maintenance as the cause. Safety concern: an engine consuming oil at this rate risks sudden loss of oil pressure and engine failure while driving, which can cause a stall or loss of power in traffic.

ENGINE AND ENGINE COOLING

The contact owns a 2018 Kia Sportage. The contact stated that while driving at an undisclosed speed, the Check Engine warning light illuminated. Additionally, the contact stated that the vehicle was experiencing excessive oil consumption, which resulted in spark plug fouling, and the vehicle exhibited an audible engine noise consistent with a potential engine failure. The vehicle was taken to an independent mechanic, where the spark plugs were serviced. The contact also reported multiple visits to the mechanic for oil additions. No further information was available. The manufacturer was not notified of the failure. The approximate failure mileage was 100,000.

I received a voluntary emissions update letter from kia, and although it was voluntary, the letter said failure to update could be considered lack of maintenance. The update was performed on XXX at Dorsch Ford/Kia in [XXX]. The vehicle ran poorly from that day forward. I gave it a couple of weeks to insure that the system could learn my driving habits. I then went to the Dorsch service department to report my issues. The service writer {Andy} said he hadn't heard of any issues with the update. I had him log in my issues to have a record that I complained. I returned several more times and talked to other service writers who told me that if they would check the vehicle and found nothing that I would have to pay service fees. the vehicle jerks and up/downshifts frequently and almost stalls sometimes when accelerating from a stoplight. It will lung periodically when navigating a parking lot at low speeds. It frequently searches for a different gear in traffic. To be clear, my car ran perfectly before this update. I asked them to put the previous tune back into the car but they said they can't do that. The car runs fine sometimes but the uncertainty of the jerking and shifting at improper times makes it dangerous to drive. Also almost stalling at an intersection is very dangerous too. I doubt that I am the only one to have this problem. Please help in any way you can to get this fixed without me having to spend money to correct a factory/dealer initiated problem Thank you for all your help.

Component or System Malfunction & Availability Component/System Failed: An unidentified component within the engine compartment failed, resulting in a sudden, catastrophic thermal event (engine fire). Odometer Reading: 100,415 miles at the time of the incident. Available for Inspection: No. The vehicle was completely destroyed by the fire and is a total loss. 2. Safety Risk Assessment The vehicle was being driven at highway speeds on a major freeway by my 21-year-old son, Brennan Font, when the incident occurred. The sudden presence of heavy smoke and intense heat entering the cabin while traveling at high speeds created an immediate, life-threatening hazard. This forced an emergency pullover on the shoulder of a busy freeway. Moments after exiting, the vehicle became fully engulfed in flames, presenting a severe risk of explosion and injury to the driver and passing motorists. 3. Verification & Third-Party Inspection Reproduced/Confirmed by Dealer: No, the sudden and destructive nature of the failure prevented any prior diagnostic testing. Inspected by Manufacturer/Authorities: The vehicle has not been inspected by the manufacturer. However, the incident was handled and documented on-scene by local authorities. A formal police report was filed by the Ventura Police Department (Report Number: 26-31369, responding officer: Officer Steinberger). 4. Warning Symptoms and Timeline There were no prior warning lamps, dashboard messages, check engine lights, or abnormal symptoms leading up to the failure. The onset of heavy smoke and heat was sudden and instantaneous. 5. Detailed Incident Description Brennan immediately steered the vehicle to the shoulder of the freeway. As soon as he brought the vehicle to a stop and attempted to park, open flames breached the hood of the car. He successfully exited the vehicle without injury and immediately dialed 911. The vehicle burned completely before the fire could be extinguished. Fortunately, no injuries were reported.

ELECTRICAL SYSTEM,EXTERIOR LIGHTING,ENGINE

The oil was leaking somewhere not on the motor not under the car not blowing black smoke. I kept adding oil to it. No oil light. I was told not to park between 2 houses or in my garage it could catch on fire. I took it in several times and they did all kinds of stuff motor wash knock sensor was replaced wiring harness was corroded was slipping out of gear and other issues. And now it doesn't run because of the motor issue and they refused to fix it because I didn't have oil change receipts they are the ones that took care of that there was no oil to change I kept adding it. I have all of the detailed work invoices of what they did to it. I've been without a car for a year now they said it's not under warranty my car has several of the recalls. They wouldn't do all of the stuff they did if it wasn't necessary and trying to locate the problem.
